Model 2000W1000B, 2000 Watts CW 80-1000 MHz The Model 2000W1000B is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 2000W1000B, when used with a sweep generator, will nominally provide over 2000 watts of RF power. The Model 2000W1000B is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a graphic display, menu assigned softkeys, a single rotary knob, and four dedicated switches (POWER, STANDBY, OPERATE and FAULT/RESET) to offer extensive control and status reporting capability. The display provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status. Special features include a gain control, internal/external automatic level control (ALC) with front panel control of the ALC threshold, pulse input capability and RF output level protection. Also included is an internal RF detector which provides an output for use in self-testing or operational modes. All amplifier control functions and status indications are available remotely in GPIB/IEEE-488.2 format, and RS-232 fiber optic. The bus interface connector is located on the back panel and positive control of local or remote operation is assured by a keylock on the front panel of the amplifier. Housed in stylish, contemporary equipment racks, the Model 2000W1000B provides readily available RF power for typical applications such as RF susceptibility testing, antenna and component testing, watt meter calibration, and as a driver for frequency multipliers and higher power amplifiers. The 2000W1000B consists of two 1000 watt amplifiers which can be operated as independent individual amplifiers and a controller/driver equipment rack. By simply adding one 1000 watt amplifier and the appropriate combiner along with minor tuning, the 2000W1000B is upgraded to a 3000 watt amplifier with expandability to 4000 watts. 2000W1000B TYPICAL POWER OUTPUT 3000 2900 2800 2700 2600 2500 2400 Power (Watts) 2300 2200 P 3dB 2100 2000 1900 1800 1700 1600 P1dB 1500 1400 1300 1200 1100 1000 Freq.
